 ## 🎨 Usage Examples
 
+### UML Class Diagram Creation
+The system now supports creating detailed UML class diagrams with:
+- **Class attributes** with types and visibility (public/private)
+- **Class methods** with return types and parameters
+- **Association relationships** between classes
+- **Automatic ID extraction** from server responses
+
+**Example**: Run the tasklist MCP client to create a sample diagram:
+```bash
+cd tasklist_mcp_client
+cargo run --bin tasklist_mcp_client
+```
+This creates a Person-Car relationship diagram with full attributes and methods.

+# WIT Composition Project
+
+This project demonstrates the composition of WebAssembly Interface Types (WIT) definitions using `math.wit`, `user.wit`, and `world.wit`. The project provides a clear example of how multiple WIT definitions can interact and be composed in Rust using the WebAssembly component model.
+
+## Project Structure
+
+```
+wit-composition-project/
+├── wit/
+│   ├── math.wit
+│   ├── user.wit
+│   └── world.wit
+└── src/
+    └── lib.rs
+```
+
+## WIT Interfaces
+
+### math.wit
+
+Defines basic mathematical operations.
+
+```wit
+interface math {
+  add: func(a: f32, b: f32) -> f32
+  subtract: func(a: f32, b: f32) -> f32
+  multiply: func(a: f32, b: f32) -> f32
+  divide: func(a: f32, b: f32) -> result<f32, string>
+}
+```
+
+### user.wit
+
+Defines user-related functionality.
+
+```wit
+interface user {
+  record User {
+    id: u32,
+    name: string,
+  }
+
+  get-user: func(id: u32) -> option<User>
+  create-user: func(name: string) -> User
+}
+```
+
+### world.wit
+
+Composes the interfaces and defines the main entry point.
+
+```wit
+world world {
+  import math
+  import user
+
+  export greet-user: func(id: u32) -> string
+  export calculate-and-greet: func(id: u32, a: f32, b: f32) -> string
+}
+```
+
+## Rust Implementation (`src/lib.rs`)
+
+The Rust library provides implementations for the composed WIT interfaces.
+
+```rust
+use wit_bindgen::generate;
+
+// Generate Rust bindings from WIT definitions
+generate!("world");
+
+struct UserService;
+struct MathService;
+
+impl world::user::User for UserService {
+    fn get_user(id: u32) -> Option<world::user::User> {
+        Some(world::user::User { id, name: format!("User{id}") })
+    }
+
+    fn create_user(name: String) -> world::user::User {
+        world::user::User { id: 1, name }
+    }
+}
+
+impl world::math::Math for MathService {
+    fn add(a: f32, b: f32) -> f32 { a + b }
+    fn subtract(a: f32, b: f32) -> f32 { a - b }
+    fn multiply(a: f32, b: f32) -> f32 { a * b }
+
+    fn divide(a: f32, b: f32) -> Result<f32, String> {
+        if b == 0.0 {
+            Err("Cannot divide by zero".into())
+        } else {
+            Ok(a / b)
+        }
+    }
+}
+
+pub struct Component;
+
+impl world::World for Component {
+    fn greet_user(id: u32) -> String {
+        match UserService::get_user(id) {
+            Some(user) => format!("Hello, {}!", user.name),
+            None => "User not found".into(),
+        }
+    }
+
+    fn calculate_and_greet(id: u32, a: f32, b: f32) -> String {
+        match MathService::divide(a, b) {
+            Ok(result) => format!("Hello User{}, the result is {:.2}", id, result),
+            Err(e) => format!("Calculation error: {}", e),
+        }
+    }
+}
+```
+
+## Usage
+
+Compile the project using Cargo with WASM support:
+
+```bash
+cargo build --target wasm32-unknown-unknown --release
+```
